What's that song in the very early episode of 'Friends'. Rachel walks into the bar, kicks the juke box and tells Chandler exactly what she wants him to do to her.
It's "Time of The Season" written by Rod Argent, performed by The Zombies (1969) according to this site:

Some
other great unanswered Friends Questions on there too. Hope this helps
